TAKE-UP MECHANISM FOR LOOMS.

Specification of Letters Patent.

Application filed May 26, 1910. Serial No. 563,485.

Patented Jan. 24, 1911.

To all whom it may concern:

1 Be it known that I, ALoNzo E. RHoAons, a citizen of the United States,and resident of I-Iopedale, county of WVorcester, State ofMassachusetts, have invented an Improvement in Take-Up Mechanism forLooms, of which the following description, in connection with theaccompanying drawing, is a specification, like characters on the drawingrepresenting like parts.

This invention relates to loom take-up mechanism .more particularly ofthe type wherein the driving member is rotated continuously andpositively while the loom is in operation, and my present invention hasfor its object the production of novel means whereby the take-up rollcan be disconnected at will from the actuating mechanism and turnedforward or backward, manually, and herein take-up is arrestedautomatically when a certain change is effected in the normal operationof the loom,

' such for instance as a change of filling.

C of the loom has fast upon it a bevel gear 1 meshing with a bevelpinion 2 fast on an intermediate shaft 3 mounted in suitable bearings onthe inside of the side frame A of the loom, the lower end of said shafthaving a bevel pinion 4 which meshes with and drives a bevel gear 5.Said gear 5, and a like gear 6, areboth fast on a counter-shaft 7carried in suitable bearings provided by a bracket 8 bolted to the loomside, the shaft 7 being parallel to the cam-shaft C but below and behindit and out of the way of other parts of the loom structure. The bevelgear 6 is at the outer side of the loom frame, as

, shown in Fig. 1, and meshes with a bevel pinion 9 fast on the lowerend of a transmitting shaft 10 mounted in bearings 11, 12 on the loomside, and it will be observed that this shaft is rotated continuouslywhile the loom 1s in o eration. A worm 13 loose on the shaft a jacentthe bearing 12, and a collar 14 rotatable with and longitudinallymovable on the shaft, constitute a clutch device, one of its parts, as14, having a projection 15 to enter a notch 16 in the other part or worm13 and effect rotation of the latter with said shaft when the clutchdevice is operative, as it is illustrated in Fig. l. The clutch membersare held in engagement by a suitable spring 17 interposed between themember 1 1 and a collar 18 fast on the front end of the transmittingshaft. The clutch is opened or released to disconnect the shaft and wormby means of a yoke 19 forming one arm of a bell-crank pivoted at 20 onthe loom side, the other and forwardly extended arm 21 of the bell-crankhaving a notched portion 22 loosely entering a longitudinal slot 23,Fig. 2, in the lower end of a link 24.

Herein I have shown my invention as applied to a loom adapted to effectautomatically a change of filling, as in United States Patent No.529,940 granted November 27, 1894 to Northrop, and in Figs. 1 and 2 thestarting or controlling rock-shaft D when turned in the direction ofarrow 100 places in operation the filling-changing mechanism, as in saidpatent. Said rock-shaft has an upturned arm d fast thereon arranged tobe swung outward by the usual fork-slide (not shown) when fillingfailure is detected, to thereby turn the rockshaft D in the directionindicated by the arrow 100, Fig. 1. The upper end of link 21 ispivotally attached to a rearwardly extended arm (8 fast on shaft D, sothat when the latter is turned to effect a replenishment of filling thelink will be lifted, to swing the bell-crank and through its yoke-arm 19separate the clutch members before referred to, so that while thetransmitting shaft 10 continues to revolve the worm 13 will remainquiescent until the link 24 is lowered. As the Worm drives the take-uproll the latter will be arrested whenever the worm is thus disconnectedfrom the transmitting shaft, as will be manifest. This temporary arrestof takeup, which is efi'ected automatically,

' nism.

prevents the formation of a thin place or streak in the cloth when achange of filling is called for. V

The take-up roll 25 mounted in usual bearings below the breast-beam Bhas an attached gear 26 meshing with a gear 27 driven by a pinion 28,the latter having an attached and larger pinion 29 meshing with a pinion30 secured to or forming part of a gear 31, this train of gearingtransmitting motion to the take-up roll from a shiftable gear 32. Thisshiftable gear is rotatable on a fixed shaft 33 mounted between the loomside A and the usual guide E for the clothroll, the said gear having anannularlygrooved hub 34 which is engaged by the inturned studs 35, Fig.3, of a yoke-like gear shifter 36 having a hub at its lower endfulcrumed on a pintle 37 carried by a bifurcated bracket 38 fixedlyattached to a part of the loom frame, such as the crossgirth F. As thepintle is at right angles to shaft 33 the gear shifter swings toward andfrom the adjacent loom side, and when swung to the left, Fig. 1, saidgear shifter slides the shiftable gear 32 to the left and out of meshwith the gear 31 of the transmitting train of gearing just referred to.This movement of the shiftable gear is effected by the weaver, thegear-shifter 36 having an attached handle 39 provided for the purpose,and return movement is effected by a spring 40 fixed at one end tobracket 38 and secured at its other end to the gear shifter, as clearlyshown in Fig. 3. A shaft 41 having at its outer end a hand-wheel 42 iscarried by a bearing 43 on a fixed stand 44, and the inner end of thisshaft has fixed on it a pinion 45, see dotted lines Fig. 1, which isalways in mesh with the gear 31 of the transmitting train. hen it isdesired to turn the take-up roll 25 either forward or backward theweaver shifts the gear 32, as described, thereby releasing thetransmitting train from the other portion of the mechanism, and by meansof the handwheel 42 the weaver can manipulate the take-up roll as may benecessary, whether the actuating worm 13 is in motion or at rest, andwithout being obliged to handle any greasy or oiled portions of themecha- The shiftable gear 32 is always in mesh with a wide faced pinion46, fast on the inner end of a shaft 47 extended through the stand 44and having fast on its outer end a worm gear 48 which is in continuousmesh with the driving worm 13, as clearly shown in Fig. 1.

It will now be clear that whenever the driving member or worm isconnected with the shaft 10 by the clutch device it will be revolved,and through worm-gear 48, pinion 46 and shiftable gear 32, thetransmitting train of gearing will be actuated to rotate the take-uproll 25, the hand-wheel 42 revolving whenever said train is operating.

When a change of filling is effected the worm 13 is unclutchedautomatically from the shaft 10 and take-up is thereby arrested untilthe rock-shaft D causes the worm to be again clutched to the shaft 10 torotate therewith.

Ordinarily there is no necessity to advance or let back the takeup rollwhen the loom is in motion, but it will be seen that were it not for themanually shiftable gear 32 it would be impossible for the weaver to movethe take-up roll by hand without first unclutching the worm 13. By themanually operated shifting device, however, the takeup roll can bereadily manipulated by hand, whether or not the worm is unclutched, forwhen the gear 32 is shifted by the weaver the transmitting train leadingto the take-up roll is wholly disconnected from the parts immediatelydriven by the worm, to wit, the worm-gear 48 and the long pinion 46. Thegear-shifter handle 39 and the manually controlled member 42 foroperating the take-up roll by hand are within easy reach of the weaver.Should the Weaver fail to bring the shiftable gear into mesh with thetrain of gearing the spring 40 will act to slide the gear 32 into meshwith the gear 31 just as soon as the teeth of one come opposite spacesbetween teeth of the other, the gear 32 always revolving at a very slowspeed when the loom is in motion.

Various changes or modifications in details of construction andarrangement may be made by those skilled in the art without departingfrom the spirit and scope of my invention as set forth in the claimsannexed hereto.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a loom, a take-up roll and a train oftransmitting gearing permanently connected therewith, manually-operateddriving means for said train comprising a shaft having a pinion on itsinner end, in continuous mesh wit-h a member of said train, and a handwheel on the outer end of said shaft, and power actuatingmechanism forthe train, including a driving member normally in continuous rotation,and a shiftable gear 'movable into and out of control of said train ofgearing, said manually operated driving means being wholly independentof and separate from the power actuating-mechanism, combined withmanually operated means to shift said gear and release the train fromcontrol thereby, and mechanism to effect antomatically temporarystoppage of the driving member to thereby arrest take-up.

2. In a loom, a shaft continuously rotated by a going part of the loom,a worm on said shaft, a clutch device to connect said worm and shaft torotate in unison, means acting through the clutch to release the wormfrom the shaft automatically, a take-up roll, operthe latter is releasedfrom control by the 10 ating connections between it and the worm, worm.including a shiftable gear always under the In testimony whereof, I havesigned my control of the worm, means to shift said gear name to thisspecification, in the presence of 5 manually to thereby release thetake-up roll two subscribing witnesses;
